Visual Inspection

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2016 Porsche Panamera, 2015 Porsche Panamera, 2014 Porsche Panamera, 2013 Porsche Panamera, and 2012 Porsche Panamera. However, it is still accessible from the selected car via links, so may be relevant.

A visual inspection of the battery must be performed before taking measurements, e.g. measuring the open-circuit voltage, or before carrying out the battery load test.

This inspection can be used to determine:

Whether the housing of the battery is damaged. The leak-free operation and function of the battery cannot be guaranteed if the housing is damaged.
Whether the battery terminals (battery line connections) are damaged. Contact of the line connections cannot be guaranteed if the battery terminals are damaged. This can cause a line fire and malfunctions in the electrical system.
